Section 445A.447 - Plans for permanent closure; sources not classified as process components

1. Plans for permanent closure are required for all sources at a facility.

2. A final plan for permanent closure of any source which has been identified as a process component must be submitted to the Department at least 2 years before the anticipated permanent closure of that process component.

3. Sources which have not been classified as process components must be evaluated at the end of their operating life to determine the potential for pollutants from these sources to migrate and degrade the waters of the State under the final proposed site conditions and must be closed in accordance with the State Handbook of Best Management Practices prepared pursuant to NAC 445A.336.

4. The Department may require the holder of a permit to revise a previously approved final plan for permanent closure if, based on new information received by the Department, the Department determines that the final plan for permanent closure will not achieve chemical stabilization, source removal or mitigation of a process component.
